First two may be a problem
Last one is Kosher for Pesach for all

Is the problem the yeast extract?

Yes. It’s probably ok, but we would need to identify the source of that yeast.

They used to have a hechshered product, but discontinued it a few years ago. I could never find out why.

Usually it’s a financial decision.
